The pedipalps are the second pair of appendages found on arachnids, such as spiders, scorpions, and mites. They are located anterior to the walking legs and are derived from the pre-oral appendages of these arthropods. While the primary function varies among different arachnid groups, the pedipalps often serve sensory, manipulative, and even locomotory roles. In many species, they can be significantly modified, featuring pincers, claws, or other specialized structures adapted for prey capture, defense, or mating behaviors. Their structure is segmented, often composed of the coxa, trochanter, femur, patella, tibia, and tarsus. The diversity of form and function makes them a valuable feature for arachnid classification.
